And how is it that we are asking these questions now and not before? Why has philosophy neglected this vital understanding of the world and human interaction? In this re-printed publication, the Dutch philosopher Herman Dooyeweerd (1894-1977) explains the analogical concepts and seeks to call attention to what has been so long neglected.
